Brief Summary:
This study evaluated and optimized settings for, and evaluated the performance of, AI-700-enhanced echocardiographic imaging on several ultrasound imaging platforms, as well as collected additional safety data for AI-700 in healthy volunteers and stable cardiac patients.
Detailed Description:
Because the quality of AI-700-enhanced images is in part determined by the ultrasound (US) settings selection, the continuing study of different imaging modes and/or techniques is required in order to provide US settings recommendations for the many available systems. Therefore AI-700-enhanced imaging was performed in this study using imaging platforms and modes not previously tested and the AI-700 dose and administration methods employed in previous Phase 3 studies.
Two cohorts of subjects were studied at each site. Enrollment commenced with Cohort A and included normal (healthy) volunteers and stable cardiac patients. Settings optimization was performed in Cohort A using a single platform and real-time imaging. If the Sponsor agreed that the images and settings acquired in Cohort A were acceptable, the site was authorized to begin enrollment in Cohort B using the platform and settings that were defined in Cohort A. Authorized sites enrolled stable cardiac patients in Cohort B; no healthy volunteers were studied. For Cohort B subjects, the first 0.04 mL/kg dose of AI 700 was used to evaluate real-time imaging with the settings defined in Cohort A. The second dose of AI-700 for Cohort B subjects may have been used to confirm the data obtained with the first dose, or to explore imaging in a second mode (e.g. 3D/4D) and/or using real-time, high mechanical index triggered imaging on a second platform.
